You may guess what it does,

Thanks,
http://www.xs4all.nl/~loekjehe/Split&Concat/ indicates that it's limited
to 2GB files but I'll try it anyway.

It is a pretty face on command line's split and command line's cat.
Sometimes it mistakenly whinges about .dmgs being directories.

I used split and cat on .dmgs without error. That also has the
advantage that you can start burning DVDs while the splitting
continues.

These days I just buy another terabyte or two of disk drive for my
tray-free monster. Life's too short to split and burn to DVDs.

Right. With HDs nearing 4 cents/GB
burning to disk is no longer worth the trouble,
excepting only stuff you really don't want to see again
for the next fifty years or so,
and want the kiddies to find,

1) Yes indeed, all households are best served by an expensive
hot-pluggable monster HDD chassis with a hundred quid or so dropped on a
new big HDD any time local backups need to be made.

Hyperbole Rowland! Compare local backups firing automatically in the
dead of night, every night for months and months of unattended
perfection with an hour or six playing postman with a hundred DVDs per
day.


2) And of course we all buy new HDDs any time we want to send stuff
through the post.
Post? What's that? Less than 10 GB it is faster to copy on line.
Broadband here is bad, but you should see the snail mail service!

3) A few GB of data (or even less, if any of you can remember such a
thing[1]) is indeed obviously best backed up to HDD - there's no
possible reason for burning set of DVDs by way of fast, secure, cheap,
and convenient multiple generation multiple location backup. Nope, best
burn to multiple HDDs and move them around the place - obviously much
cheaper and more convenient than writing to removable media costing a
few pence a pop.
The sums don't work. 2TB of DVD costs the same as a HD. 2TB of DVD
occupies 5 litres of cupboard space. The disk about 500ml. Operator
time per 2TB disk backups approaches epsilon. Operator time for 2TB of
DVD is about 1 week 24 hours/day to write and read back.

4) And naturally, since typical writable DVDs show signs of data loss
through aging after 5-10 years, they're perfect for long-term archiving.

Rowland.

[1] My documents folder is 2.49GB...
OK. That explains it. Different strokes for different folks. My
Aperture Libraries and vaults total 2.5TB, My movie clip permanent
storage is 1TB, my music is 400GB
oh, and my documents folder is 20GB.
DVDs, even Blu-Ray disks, are out of the question. Far too small and
far too fiddly.

I automatically backup the boot disk daily with Superduper! Time
Machine handles ~/Documents ~/Library and such. Separate SuperDuper!
schedules for music and movie clips. Aperture Vaults are manual
operations with a fortnightly offsite for one of them and for new movie
clips.

All of this is relatively handsfree, possibly 1 minute per day and a
bit of waiting once a fortnight. If I were doing it on DVD, it would
take a fortnight per day.
